The most reliable cross membered bullet made today, Remington Premier A-Frame centerfire ammunition is virtually custom made for situations where there can be no compromise in ammunition quality, reliability, or performance. Whether it's whitetails with a 270 Win, or Cape Buffalo with a 416 Remington Magnum, you want your first shot to do the job. That's why Remington loads the dual core A-Frame bullets, so that you can expect reliable expansion at long range decreased velocities, but without over expansion at short range high velocities. The combination of A-Frame construction and proprietary bonding process produces extremely uniform, controlled expansion to 2x caliber with nearly 100% weight retention. All Premier A-Frame components receive multiple inspections: primers are pre inspected five times for ignition reliability; each round is receiver gauged, and cases are nickel plated for precision feeding and extraction. You simply can't buy a better factory loaded medium to big game ammunition.
